See a larger version of this image.Scientists and reindeer herders in Norway have teamed up to help each other understand the impacts of climate change.

Nancy Maynard: _Recently, there have been serious declines in number of reindeer, and very directly impacting the well-being of the indigenous people associated with them. Part of that is due to warmer temperatures and climate changes generally._

That’s Nancy Maynard, a scientist at the Goddard Space Flight Center. She works on a project with the Norwegian acronym “EALAT”:http://www.ip-ipy.org/.

For hundreds of years, the Sámi people of northern Norway have herded reindeer across the frigid Arctic. But higher temperatures have melted and refrozen snow to make ice layers, which make it hard for the reindeer to forage for food. And the herders worry about melting in frozen lakes along the way.

In the EALAT project, the reindeer herders take measurements of snow temperature and observe the year-to-year changes. Maynard combines that information with satellite data to create a real-time record of climate change in the Norwegian Arctic.

The Sámi people of Norway depend on reindeer for food. Maynard said the EALAT project will help ensure the reindeer’s survival and help preserve their culture.
